The Ion and Electron Sensor (IES) for the Rosetta Mission to Explore a Comet

The IES instrument is one of 15 scientific instruments onboard the European Space Agency's (ESA's) Rosetta Spacecraft, on its way to explore the comet 67P/Churyumov-Gerasimenko. IES is a member of the Rosetta Plasma Consortium (RPC), a group of 5 plasma instruments that make up the payload. The spacecraft was launched March 2, 2004 from Kourou, French Guiana, and will reach the comet in 2014.

IES was designed and developed and is operated by the Southwest Research Institute to study the plasma environment of the comet as well as interplanetary space. This work is supported in part by the National Aeronautics and Space Administration through the Jet Propulsion Laboratory.
